While I'm not pissed or disappointed, I do understand the problem some people have with this.
At first, Bioware basically said: Pre-order now, and you can play 5 days early. PERIOD.
I think it was after a few weeks, or even DEEPER between the lines, where it said that there was a maximum of 5 days early depending on how soon you pre-ordered.
Understand how people pre-ordering the game a week or one month ago without reading the fine-print feel when they realize they have a... what, 2 hours or 1 day earlier game access.
I gotta say, my patient demeanor will transform into one of fury and impatience when I haven't got an invite before this friday. I'll try to stay far away from the forum if that's the case.
